The actress took to Instagram yesterday to post a picture of herself sitting in a restaurant booth with her hand outstretched, as if to say "no pictures!" But it's not the photo that has caught the attention of fans; rather, it's the caption — and who is tagged. "When I wanted eggs and toast at 1am," Lili wrote alongside the photo, tagging Cole in the background.

Taking those "clues" into consideration, it definitely seems as though Lili and Cole went on a late-night diner run for a midnight breakfast. Cole, being the photographer that he is, might have snapped a photo of his costar while they were waiting for their food. There's no way to know for sure, but this is the scenario that fans seem to be imagining — along with a side of romance. "The ship is sailing!" one fan wrote in the comments with a heart emoji for emphasis. "Sprousehart confirmed?" another mused, adding: "I think yes."

Despite all the rumors, neither Lili nor Cole have confirmed their relationship status. When asked about it in an interview, Cole simply said: "Truthfully, it’s very pleasing that people talk about Lili and I in that way because it means that we’re resonating so strongly that people really want that to be true." Until we hear more from them, we won't definitively know whether or not "Sprousehart" is for real. Regardless, it seems as though they have a lot of fun together off-screen, which is the most important thing. After all, having someone to eat eggs with at 1 a.m. is valuable no matter what.
